Abstract
In an information processing system for efficiently allocating a writing of a decoded pixel signal into a display memory to a period other than the period during which a read circuit accesses the display memory for reading out information to a display device for a display, the read circuit indicates to a decode/write circuit producing the decoded pixel signal a period during which the read circuit does not access the display memory, and the decode/write circuit writes the decoded pixel signal into the display memory at a timing at which the display memory is not accessed by the read circuit.
